The invention relates to insecticidal mixtures for protecting plants against attack by pests comprising compounds of the formula \u2003in which W, X, Y, Z, A, B, D and G are each as defined in the disclosure, and agonists or antagonists of nicotinic acetylcholine receptors. The service includes a schema that defines rules and a structure for each user’s data, and also includes methods that provide access to the data in a defined way. The error amplifier compares the target voltage and the measurement voltage and outputs a signal for controlling the voltage regulators. An atomic clock is disposed in or with the seismic receiver for time-stamping a record of the detected seismic signal. Douching fluid discharged into the vaginal canal is directed proximally along a plurality of external head channels of the head toward a plurality of external body channels of the applicator body. Alternatively, the recirculation system is arranged substantially internally within the cylinder head.
